Title: Method and unit for displaying the electrical activity of the brain
Inventor: MISZCZAK JAN
IPC: G06F17/00
Filed: 1987-10-14
Abstract: The subject matter of the invention is a method and a unit for displaying the electrical brain activity, in particular the resting, electrical brain activity EEG, the induced electrical brain activity EP and the spectral energy of the electrical brain activity, which are applied in medicine, in diagnostics and for research purposes. The display of electrical brain activity is based on the generation of an input data matrix composed of the electric signals which are received by the sensors of the electrical brain activity, which matrix is utilised thereafter to generate an extended image matrix having a number of components whose number is larger at least by one row than the number of the sensors. The extended image matrix is subsequently displayed on the colour monitor as a topographic map of the electrical brain activity, as a coloured image or as isolines of the signal variations originating from the sensor, which are represented in the X, Y coordinate system. The unit for carrying out the method contains an implementing unit (19) to which a programmed computer (20) is connected from one side and an amplifier (18) of the biological signals is connected from the other side. <IMAGE>

IPC: H04M11/06
Filed: 1987-10-22
Abstract: Using the novel method, it should be possible to achieve the highest possible data rate for the data to be transmitted in addition to speech. For this purpose, the voice frequency band is split into at least two part-frequency bands at the transmitter end. The part-frequency bands are scrambled with one another and optionally inverted or not inverted. For the simultaneous transmission of additional data, the speech information of at least one part-frequency band is also removed at the transmitter end and replaced by the data to be transmitted. At the receiver end, the part-frequency bands are inverted again or not inverted and descrambled in corresponding inversion with respect to the transmitter end. Finally, the part-frequency bands used for the respective transmission of speech or of additional data are selectively separated and separately evaluated. Simultaneous speech and data transmission.

Title: Hydrogen/oxygen fuel cell with catalyst electrodes in the form of packings
Inventor: HAGER GERHARD DR
IPC: H01M8/00
Filed: 1988-04-27
Abstract: The long-term behaviour of hydrogen/oxygen fuel cells containing Raney nickel, palladium black or platinum black as electrocatalysts can be substantially improved yet further by employing a chemical reaction, following the adsorptive hydride formation, with the catalyst support, in order to store the hydrogen to be burnt electrochemically. To this end there are used, as the hydrogen electrode (-), porous packings made from (sawdust + hydrogenation catalyst + sodium hydroxide solution + hydrogen) or packings from (redox resin + hydrogenation catalyst + sodium hydroxide solution + hydrogen). The hydrogen electrode in the form of a packing is coupled ion-conductively, via a plurality of layers of sodium hydroxide-impregnated filter paper (F) and a coating of sodium hydroxide gel, with the porous oxygen electrode (+) in the form of a packing, made of (electrographite powder + sodium hydroxide solution + oxygen). The electrode combination functions; it results in an industrially usable hydrogen/oxygen fuel cell. The reversibly reducible chemical double bonds of the catalyst support matrix (-) comprising sawdust or redox resin are converted into the H form by the hydrogenation catalyst. Consequently, the entire mass of the hydrogen electrode packing (-) behaves, with respect to the coupled oxygen electrode (+), as a strong reductant or as a constantly regenerating electrode metal (-) and can, correspondingly, ...

Title: Device for the fully automatic drive of an automatic accompanying device connected to a zither
Inventor: HILKERSBERGER MARTIN
IPC: G10H1/36
Filed: 1988-07-26
Abstract: Until now, the automatic accompanying device has been driven via a pedal (manual) keyboard by means of pressing a key corresponding to the bass string or accompanying string played. Obtaining the current information presupposes the elimination of the following disturbing variables. A played string continues to sound. When releasing a string, the finger collides with the neighbouring strings. The fingers of the player simultaneously touch a plurality of strings. The vibration of a string is recorded by infrared movement detectors. Static changes are suppressed by a filter. If a string is released, the signal reaches an evaluating TTL logic circuit via an amplifier stage. An output stage drives the automatic accompanying device via electrically insulated path. Use by solo zither players (about 500 alone in the Federal Republic of Germany). <IMAGE>

Filed: 1988-09-14
Abstract: The gas-fired boiler with an atmospheric burner consists of a cylindrical, water-cooled combustion shaft (1), in the lowermost region of which there are arranged the atmospheric gas burner (2) and there above a displacer insert (4), which bounds a hot gas drawing duct (3) having an annular cross-section and subdivided by ribbing, and is connected to the water-cooled combustion shaft (1), and above which a waste gas collecting chamber (5) with waste gas exhaust nozzles is located. According to the invention, the displacer insert (4) is formed from two shells (6, 7), which can be assembled in a liquid-tight fashion and are formed from a condensate-proof casting "released in the green state". In this arrangement, the lower shell (6) on the burner side has at least one cast-on projection (8) for the connection of at least one inflow duct (9), which connects the displacer insert (4) to the water-conducting double jacket of the combustion shaft (1). The lower (6) or the upper shell (7) likewise have at least one cast-on projection (8) for the connection of at least one inflow duct (10), which connects the displacer insert (4) to the water-conducting double jacket of the combustion shaft (1). The lower shell (6) is provided, at least in the region of the hot gas duct (3), which has a circular cross-section, with cast-on enlargements (11) of the heat transfer surfaces in the form of longitudinal ribs (12), which engage the interstices (13) of longitudinal ribs (15) arranged on the burner shaft wall (14). <IMAGE>

Title: Coin-operated gaming machine with a coin-collecting device emptyable by the operator
Inventor: GAUSELMANN PAUL
IPC: G07F9/08
Filed: 1988-10-07
Abstract: For a coin-operated gaming machine (1) with a closable coin-collecting device (6) which can be emptied by the operator and the coins of which have passed passage sensors (7) specific to particular coin values, and with a play device (9 to 11), the game sequence of which can be sequenced via actuating members, game successes being recognised and retained on a result counter (11), in order, when the predetermined count is reached, to transmit a grant signal to a coin-operated machine (13) which offers different performances and has its own cash-collecting device and which is then switched ready for performance, without the insertion of a coin, it is proposed that the coin-collecting device (6) contain two respectively separately closable coin cassettes (20, 21), to which the coins are guided by a switch (16) which, after the grant signal is activated by a counting circuit (15) indexable by the passage sensors (7) according to particular coin values, is changed over in order to guide subsequent coins into one (21) of the coin cassettes (20, 21), until these have reached the value of the performance obtained and the counting circuit (15) resets the switch (16). <IMAGE>

Title: Package and top label for attachment to the end face of a package
Inventor: PIETZSCH HEIKO
IPC: B65D75/12
Filed: 1988-10-27
Abstract: Vacuum packs made of a composite film serve to receive, in particular, consumables which are sensitive in terms of aroma, for example roasted coffee. The package consists of a film tube with a transversely directed closure seam formed by welding the film in the region of a fin fold whose triangular fold gussets are folded inwards against the end face of a block of coffee and covered by a stuck-on top label (18). To open the package, at least one of the fold gussets has to be unfolded, in which case the top label firstly has to be removed. For this purpose, the consumer usually has to use a tool. It is proposed to provide a tearing tab (19) which is connected to the upper fold gusset so that, when the tearing tab (19) is pulled upwards, thus tearing open or tearing off the top label (18), the fold gusset (13) below can be lifted up. <IMAGE>

Abstract: The invention relates to a process for preparing 1,2-naphthoquinone-(2)-diazide-4-sulfonic acid esters of the general formula I   <IMAGE> (I)  which are substituted in at least one of the positions 5, 6, 7 or 8 by R=halogen, alkoxy groups or alkoxycarbonyl groups and in which X denotes an aryl group. The process comprises steps in which a) suitably substituted  beta -naphthol is nitrosated, b) sulfonation with alkali hydrogensulfite and acid in position 4 and reduction are carried out, c) the naphthalenesulfonic acid derivative is oxidized, d) the 1,2-naphthoquinone-4-sulfonic acid formed is reacted with toluenesulfonohydrazide in an organic solvent at temperatures from 20 DEG  to 100 DEG  C., e) the naphthoquinonediazide compound is converted with chlorosulfonic acid or chlorosulfonic acid/thionyl chloride into the sulfonyl chloride, and f) the sulfonyl chloride is condensed with a phenolic component, a purification of the respective intermediate product by reprecipitation or recrystallization being unnecessary. The process makes a simple technical procedure possible with good yield. The compounds prepared, in particular the 1,2-naphthoquinone-(2)-diazide-4-sulfonic acid esters substituted by 6-alkoxycarbonyl groups or by 7-alkoxy groups, are used as radiation-sensitive components in radiation-sensitive mixtures.

Title: Method for taking off floating material from gravity separators
Inventor: LOSERIES HANS GEORG
IPC: E03F5/16
Filed: 1988-11-05
Abstract: The invention relates to a method for taking off floating material, in particular fats and other highly viscose oils, from gravity separators via an overflow edge. Separators which function with a take-off channel which can be lowered or a weir cannot be completely emptied because the clearing pressure is lacking. This disadvantage is now eliminated in that the space taken up by the floating material layer, which rises owing to damming of the water level, is spatially concentrated towards the overflow end. As a result, a sufficiently large clearing pressure is formed. A rigidly arranged inclined baffle is preferably used which ends above the overflow edge.

Title: Apparatus and process for scrubbing and purifying exhaust gases or exhaust air by foam
Inventor: GEIER-HENNINGER KURT
IPC: B01D53/34
Filed: 1988-11-07
Abstract: The patent application relates to a process for scrubbing and purifying exhaust gases or exhaust air by foam. The essential steps of the process are:   a) Inclusion of the exhaust gases or exhaust air in the foam bubbles building up the foam. b) During the dwell time in the foam bubbles, adsorption of the pollutants to the surface of the foam bubbles, transfer into the liquid phase and - depending on chemical composition - chemical reaction (conversion) of the pollutants.   c) Bursting of the pollutant-laden foam at a foam braker.   d) Filtration of the pollutant-laden liquid with a paper filter. e) Recycling and reuse of the filtered liquid in the foam injector.     The foam is generated by a foam injector which forces the exhaust gases or exhaust air through a waterbath which contains a foaming agent (frother) and possibly other additives (e.g. alkali solution or acid). The foaming agent used is particularly suitable for building up a foam which contains enclosed exhaust gases or exhaust air and withstands high counter-pressure, from which particularly small foam bubbles can be formed and foam masses several metres high can be produced in vessels. As a result of the foam being built up from particularly small foam bubbles, the active exchange surface area, essential for the purification efficiency, between gas phase and liquid phase is maximised.

Title: Protection device for openings, using grid-shaped (grate-shaped) barriers
Inventor: DROSTE DIETER
IPC: G08B13/12
Filed: 1989-01-13
Abstract: The invention relates to mechanical protection devices for openings, e.g. window grates which can be monitored electronically by means of a mechanical-electronic coupling. Figure 1 shows the main features of a mechanical-electronic solution which can be used for monitoring a window grate. Only this mechanism makes this mechanical protection device important in terms of safety since during the attempt to destroy or lever out this grate an electronic message is produced and thus an assistance can arrive in time before the burglar could overcome the grate. A mechanically movable fastening part, tensioned by a spring, is fitted to at least one grate mounting of the window grate. This moving part is connected to a microswitch which, during the attempt to lever out and thus during the displacement of the moving fastening part, is opened. In this way, this signal is passed on to an alarm system where it is transformed into a message to a point providing assistance. <IMAGE>
